The 10 Most Popular DB Engines (SQL and NoSQL)

How to objectively measure the popularity of a DB engine? Good question! And there’s an Austrian company (Solid IT) who claims to have the answer. The company focuses on “Big Data und NoSQL“, but this focus does not seem to have biased the result of the measurement. Among the top 10 database engines, there is only MongoDB, which is not an RDBMS. And it’s astonishing just how popular MongoDB seems to be (although, they must be doing something right)!

Now, I’m not surprised by the top 3. I am definitely surprised by the fact that PostgreSQL and SQLite are not more popular. I am also surprised, that there aren’t more “wide-column stores” among the top 10. Maybe, Michael Stonebraker has to review his claims about the traditional RDBMS wisdom being all wrong?

And what about the other databases supported by jOOQ? Where are the Java databases? Here’s a condensed view of the ranking, consisting only of the 15 databases currently supported by jOOQ 3.1:

There are very organizations that need the scaling of Cassandra, HBase and other NoSQL databases. Look Facebook still uses MySQL (with lots of Memcached) and the recent MySQL 5.7 numbers show 500k qps – double that of 5.6 (which was better than 5.5). There are very few companies that need that level of scaling.
